Getting strange low output voltage at Motors

Hello Everyone,
Our team PowerX had taken part in Smart India Hackathon 2022 where in we choose a problem statement.
So in our project we have used a Motor driver L298N for starting the motors.
Previously we got a too good output at Motors .
After that we added a Ultrasonic to the circuit and the code, after which we are not getting a proper voltage .
So plz help us with your ideas.

I have a question, how you suppose anyone is going to know what the hell you are talking about?

I have Arduino board and it worked great, then I changed something and it doesn’t work any more, could you help me, have you got any ideas, please?

More info…

Schematic, wiring block diagrams including power supply wiring and types.

Code - in code tags, then we’ll take your question seriously.

Please provide your code (do not forget use the code tags for inserting code to the forum) and complete schematic of your wirings

Hi, @killzone_kid
Welcome to the forum.

How are you powering your project?
Do you have a DMM?
Plus everything in post #4.

Can you please tell us your combined electronics, programming, arduino, hardware experience?

Thanks.. Tom... :smiley: :+1: :coffee: :australia:
